The thing is, why would you need an update though?
99% of devices don't need to be updated ever.
I mean if this is a crireria for you, fine, but why?
Well, all respectable compagnies work on continuous improvements.
Look at Holo Audio, Chord, Denafrips, Lumin, Mola Mola, Gustard, "throw any name here"... I mean just all of them...
Except for T+A DAC 200.
Something that is not upgradable is just stuck in the past.
Computers, phones, even cars are user-upgradable now... I mean, it is 2023.
For the owners, like you might be, Thanatos, this is not protecting your resale value.
With upgrades, a 2021 remains the same as a 2023 unit.
Without upgrades, a 2021 unit remains a 2021 unit.
How obvious is it to state that user-upgradable is better than non-upgradable.
Something must have forgotten in the development phase.
Hence the production of the cable, as a clumsy afterthought.
And talking about statistics, I am pretty sure 90% of the users who can do user-upgrades do apply the upgrades (just look at the other forums... everyone upgrades).
This kind of gear is for audio-tech savvy people from the start.
I mean, who buys a $6000 DAC without being digital-minded anyway ?
